Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515326, here are decompositions:

3 + 515323 = 515326
47 + 515279 = 515326
89 + 515237 = 515326
173 + 515153 = 515326
239 + 515087 = 515326
359 + 514967 = 515326
467 + 514859 = 515326
479 + 514847 = 515326

Showing the first eight; more decompositions exist.
